DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD16781
480 OUTPUT TFT-LCD SOURCE DRIVER
DESCRIPTION
The µ PD16781 is a source driver for 480-output TFT-LCDs, providing support for only striped pixel array LCD.
The driver consists of a shift register for generating the sampling timing and sample & hold circuits for sampling the
analog voltage. The high picture quality obtained by the alternate sample & hold execution of the two types of on-chip
sample & hold circuits enables employment in applications such as car navigation panels.
FEATURES
• 5.0 V Drive (Dynamic range 4.6 VP-P, VDD2 = 5.0 V)
• 480 Output channel
• fCLK = 20 MHz MAX. (VDD1 = 3.0 V)
• 1-phase/3-phase sampling clocks supported
• Corresponds only to LCD of Stripe array color filter
• Two on-chip sample-and-hold circuits
• Small output deviation between pins (deviation between chip pins: ±20 mV MAX.)
• Switch between right and left shift using the R,/L pin
• Logic power supply voltage (VDD1): 3.0 to 5.5 V
• Driver power supply voltage(VDD2): 5.0 ± 0.5 V
Remark /xxx indicates active low signal.
